I’d like to add a small amount of text before or after the price on the single product page template.

My eCommerce site is for renting equipment so ideally I would like a nice and clear method for adding the text ‘per week’ somewhere on the product page. Preferably next to the price so that it is clear that this is the price per week.

I’m sure it’s just a matter of editing some PHP files but I’m unsure of the correct place to look.
